Question

The ratio of the sides of a rectangle is 3:5 and the perimeter is 120 in. Find the length of the rectangle.

Answer 1

Solution

Given;

⇒Ratio of the side of rectangle is 3;5

⇒The perimeter of rectangle is 120 Cm

To Find;

⇒The length of the Rectangle

We Can  write as

⇒Length of rectangle is 5x

⇒Breadth of rectangle is 3x

Formula

⇒Perimeter of Rectangle is 2(Length + Breadth)

Now

Perimeter is given we can write as 2(Length + Breadth) = 120Cm

⇒2( 5x + 3x ) = 120

⇒2( 8x ) = 120

⇒16x = 120

⇒x = 120/16

⇒x = 7.5 Cm

So we get

⇒Length of rectangle is 5x = 5 × 7.5 = 37.5 Cm

⇒Breadth of rectangle is 3x = 3 × 7.5 = 22.5 Cm
